Network 100 can provide wireless by single carrier wave or by the polymerization (that is, carrier wave polymerization) of different component carriers Communication.Different component carriers can in different bands or within the same frequency band.For example, network 100 can support it is more A low frequency (low frequency, LF) component carrier, multiple high frequency (high frequency, HF) component carriers or LF component The polymerization of the carrier wave of carrier wave and HF component carrier.

Different component carriers can be quasi- co-located (or being total to position) or positioned at different position.Fig. 2 shows bases The figure of the network 200 for wireless communication of one embodiment, wherein different component carrier standards is co-located.As shown, network 200 TRP202 and TRP204 including being co-located at same position.TRP202 and TRP204 respectively on LF carrier wave and high frequency carrier with Multiple UE206 communication in overlay area 208.In this way, LF carrier wave and high frequency carrier standard are co-located.Fig. 3 is shown according to another reality The figure for applying the network 300 for wireless communication of example, wherein different component carriers is located on different positions.300, network It holds on two different high frequency carriers by TRP302 and TRP304 offer and on the LF carrier wave provided by TRP306 and more The wireless communication of a UE.As shown, TRP302,304,306 are located at different positions, TRP302 provides overlay area 308, TRP304 provides overlay area 310, and three TRP provide overlay area 312.TRP302 is connected to via return network 314 TRP306, TRP304 are connected to TRP306 via return network 316.

Connected in general, LF carrier wave can provide big covering with robust, but data rate is relatively low, and high frequency carrier by In it with roomy, high data rate can be provided.However, since path loss is big, HF carrier wave usually covers small, and passes in HF Also link robustness is considered in defeated.Component in the new radio of 5G (NR), due to the introducing of high frequency, in multiple carrier operations The characteristic of channel of carrier wave may be substantially different.In particular, millimeter wave high frequency (HF) link inherently suffer from big path loss and with Machine obstruction.In order to compensate for path loss, using beam forming technique, wherein forming multiple high-gains sends and/or receives wave beam For sending and receiving wireless signal.Each wave beam can be placed only in the zonule on angular direction.Wave beam can be described as guided wave Beam.Therefore, become high orientation by being formed by the transmission of wave beam progress.Beam forming can be used for by different directions The covering large area that (may be on different time-gap) forms multiple wave beams to simulate omni-direction transmissions or within the scope of certain angle Transmission.In high-frequency communication, a large amount of antenna oscillators are needed to obtain enough transmission/reception gains.At this point, for example, being used for In the wave beam identification of initial access, or it may cause very big open in the wave beam management for the communication in connection status Pin.

Wave beam management can be executed to manage the beam forming process of the side UE or the side TRP.It is counted according to third generation affiliate (3GPP) technical report (TR) 38.802V2.0.0 (2017-03) is drawn, content is incorporated herein by reference in its entirety, NR In wave beam management be defined as (referring to 6.1.6.1 save):

One group of L1/L2 process, for acquiring and maintaining can be used for downlink (DL) and uplink (UL) send/it is received The set of TRP and/or UE wave beam includes at least following aspect:

Wave beam determines: the Tx/Rx wave beam for TRP or UE selection their own.

Wave beam measurement: the characteristic of received beam-formed signal is measured for TRP or UE.

Wave beam reports: information of the UE based on wave beam measurement report beam-formed signal.

Sweep beam: wave beam sent during time interval with predetermined way and/or received covers the operation of area of space.

It (is saved), is supported in one or more TRP following referring to 6.1.6.1 according to 3GPPTR38.802V2.0.0 DLL1/L2 wave beam management process:

It has been shown that when the polymerization of multiple HF carrier waves, if two TRP (each TRP provides communication service on HF carrier wave) It is quasi- co-located, and when two high frequencies are sufficiently close to each other, two HF carrier waves show that similar receptions power is distributed in the spatial domain. In one example, survey of the UE on two HF component carriers in the domain space angle of arrival (AoA) to power is received can be obtained Amount, to show similitude.In this example, two HF component carriers are co-located at the TRP's and 28GHz as indoor hot spot In frequency band.Carrier wave 1 has the bandwidth of 200MHz in 27.9GHz, and carrier wave 2 has the bandwidth of 200MHz in 28.1GHz.Fig. 4 be In the case where depending on logical (line-of-sight, LOS), curve graph that the reception power on two HF component carriers changes with AoA 400.X-axis indicates AoA with degree, and y-axis indicates to receive power with dB.Fig. 5 be non-view it is logical (none-line-of-sight, NLOS in the case where), curve graph 500 that the reception power on two HF component carriers changes with AoA.As shown in Figure 4 and Figure 5, The power distribution of two HF component carriers is closely similar each other in the domain AoA.In general, carrier wave in the case where LOS, more than 95% Difference power between 1 and carrier wave 2 is less than 4dB；Difference power in the case where NLOS, between the carrier wave 1 more than 90% and carrier wave 2 Less than 4dB.Fig. 6 be shown respectively in LOS and NLOS two HF component carriers the difference received between power it is tired The curve graph 600 of product distribution function (cumulative distribution function, CDF).As shown, LOS and CDF in the case of NLOS is also very close to each other, and LOS or NLOS do not influence the power distribution spy of two HF component carriers Property.

Example shown in Fig. 4 to 6 is shown, and in the case where more HF carrier operations, can be built across two HF component carriers Vertical space QCL (according to downlink beamforming profile).At this point, the wave beam management information of a HF component carrier is (for example, receive function Rate) it can at least partly be reused in another wave beam management, to reduce wave beam administration overhead.

Embodiment of the disclosure points out, when two or more HF component carriers are usually spatially quasi- co-located (or in space Upper quasi- position altogether) when, or when that can cross over two or more HF component carriers and establish space QCL, two or more HF components Carrier wave has similar beam profile.At this point, the wave beam management information of a HF component carrier can be at least partly by another A HF component carrier uses in executing wave beam management process, or at least can be used for or help to execute wave beam management stream each other Journey.In general, under two following situations, two HF component carriers are spatially quasi- co-located: 1) component carrier coexistence is (or altogether Position)；2) component carrier is closer to each other in frequency.In some embodiments, the reference signal (example in a HF component carrier Such as synchronization signal (SS), CSI-RS or demodulated reference signal (DMRS)) it can be used for dividing in the quasi- co-located HF in another space Reference signal (such as SS, CSI-RS or DMRS etc.) in loading gage wave is co-located in space standard.In some embodiments, when HF component When carrier wave and LF component carrier coexist, space QCL can also be established across HF component carrier and LF component carrier.At this point, LF points The relevant information of loading gage wave, such as arrival direction (direction of arrival, DoA), also can contribute to or for holding The wave beam management of row HF component carrier.In some embodiments, the reference signal in HF component carrier (such as SS, CSI-RS or DMRS etc.) can be used for it is spatially quasi- co-located with the reference signal (such as SS, CSI-RS or DMRS etc.) in LF component carrier.

Reference signal when two carrier waves (for example, carrier wave 1 and carrier wave 2) are spatially quasi- co-located, in a carrier wave (RS), such as SS, CSI-RS, DMRS etc. can be used for spatially quasi- co-located with another RS in another carrier wave.Example Such as, the CSI-RS in carrier wave 1 can be used for spatially quasi- co-located with the CSI-RS in carrier wave 2.In another example, carrier wave CSI-RS in 1 can be used for spatially quasi- co-located with the SS in carrier wave 2.In yet another example, the SS in carrier wave 1 can be with For spatially quasi- co-located with the CSI-RS in carrier wave 2.In yet another example, the SS in carrier wave 1 can be used for and carrier wave 2 In SS it is spatially quasi- co-located.RS in the disclosure can refer to SS (or SS block), CSI-RS, DMRS, Phase Tracking with reference to letter Number (PTRS), track reference signal (TRS), interception reference signal (SRS), or used in wireless communication it is any other with reference to letter Number.

Space QCL is established on multiple component carriers to advantageously reduce wave beam administration overhead, simplify wave beam management process, improve Communication efficiency is improved service quality and user experience.These advantages may include shortening the beam scanning time, reduce wave beam management Power consumption faster determines wave beam, shortens transmission latency, and reduce expense relevant to wave beam management reference signal etc..

Beam profile may include during wave beam management process generate or obtain wave beam management information, or with wave beam management Relevant information.The example of wave beam management information may include the measurement of UE report, such as Reference Signal Received Power (RSRP) With Reference Signal Received Quality (RSRQ), downlink and/or uplink beam group, downlink and/or uplink wave Beam, downlink and/or uplink beam angle, such as AoA, wave beam send wave beam and connect to link (BPL), such as a pair Receive wave beam, reference signal, beam power and beam gain.For example, can be obtained during the wave beam of UE measures and reports process The RSRP or RSRQ of TRP transmission wave beam.In another example, BPL can be generated during wave beam determines process, and wherein TRP is determined Or selection is determining corresponding to the reception wave beam or in which UE of the transmission wave beam of UE or selects connecing for the transmission wave beam for corresponding to TRP Receive wave beam.Relevant information managed usually to wave beam may include the direction of signal that is received or sending.When in wave beam management When period determines beam scanning region or transmission/reception wave beam, the direction can be used.

It is configured using establishing space QCL on multiple component carriers, and/or between the reference signal of multiple component carriers The wave beam management information of space QCL, one-component carrier wave can use during the wave beam management process of another component carrier Or it reuses.In one embodiment, when two HF component carriers (for example, carrier wave 1 and carrier wave 2) are spatially quasi- co-located When, for downlink beamforming management, TRP can be right in the region that the RSRP (or RSRQ) for being based upon the report of carrier wave 2 is determined Carrier wave 1 executes downlink beamforming scanning (for example, process P-1).RSRP (and/or RSRQ) can be based on to corresponding downlink The UE of reference signal (such as SS, CSI-RS or DMRS etc.) is measured.For example, TRP can based on UE report RSRP (and/or RSRQ) TRP in discriminatory carrier 2 sends wave beam, and sends wave beam based on the TRP in carrier wave 2 and determine region.In another implementation In example, TRP or UE can skip process P-1, and start process P-2 and/or P-3 based on the BPL for being the determination of carrier wave 2, To select the refinement TRP for carrier wave 1 to send wave beam, and/or refinement UE of the selection for carrier wave 1 receives wave beam.In another reality It applies in example, TRP or UE can be configured the transmission wave beam in carrier wave 1 based on the wave beam management information of carrier wave 2 or receive wave beam.

In some embodiments, the first RS (such as CSI-RS, DMRS or SS block) in carrier wave 1 can spatially with load The 2nd RS (such as CSI-RS, DMRS or SS block) in wave 2 is quasi- co-located.It is had been used at this point, TRP can be based at least partially on The RS of carrier wave 2 is configured to the first RS of carrier wave 1.In an example of CSI-RS, the CSI-RS of carrier wave 1 and carrier wave 2 can With different periods or density.For example, the CSI-RS of carrier wave 1 can have periodicity longer than the CSI-RS of carrier wave 2. In another example, the CSI-RS for carrier wave 1 can have than the lower frequency density of carrier wave 2.First RS's of carrier wave 1 matches Setting may include information about the resource unit for carrying RS, such as resource in the quantity and/or resource block of resource unit The position of unit.The information of space QCL between specified first RS and the 2nd RS can also be for example via RRC, MAC-CE, DCI Signaling or combinations thereof is sent to one or more UE, and in carrier wave, such as in carrier wave 1 or carrier wave 2.When TRP is by carrier wave 1 In the first RS resource in the first RS when being sent to UE, UE can be configured based on the RS in carrier wave 1 and at least partly ground The 2nd RS in carrier wave 2 carrys out the first RS in detected carrier 1, and wherein the first RS in carrier wave 1 is spatially and in carrier wave 2 2nd RS standard is co-located.In one example, UE can determine that the identical reception wave beam for receiving the 2nd RS in carrier wave 2 can be with For receiving the first downlink RS in carrier wave 1, wherein the first RS in carrier wave 1 spatially with the 2nd RS in carrier wave 2 It is quasi- co-located.In another example, wave beam may be selected to receive the first downlink RS in carrier wave 1 in UE, and wherein the wave beam has There is spatial character identical with for receiving the wave beam of the 2nd RS in carrier wave 2 (for example, beam direction, beam forming gain, wave Beam width etc.), and the first RS in carrier wave 1 and the 2nd space RS standard in carrier wave 2 are co-located.In these cases, UE is not needed From the beginning the reception wave beam (for example, process P-1) in carrier wave 1 is detected and determined, therefore avoids a large amount of wave beam detection overhead.

In some embodiments, configuration TRP wave beam may include the RS that configuration represents TRP wave beam.When two carrier wave (examples Such as, carrier wave 1 and carrier wave 2) it is spatially quasi- co-located each other when, TRP can be based on for the 2nd TRP in the carrier wave 2 with UE communication Wave beam configures the first TRP wave beam in carrier wave 1 to be used for and UE communication.In one embodiment, TRP can be at least partly The first RS for representing the first TRP wave beam in carrier wave 1 is configured based on the 2nd RS of the 2nd TRP wave beam represented in carrier wave 2.The One RS is spatially co-located with the 2nd RS standard.First TRP wave beam can be TRP and receive wave beam or TRP transmission wave beam.In an example In, TRP can send the first RS in the first TRP wave beam of carrier wave 1 to UE, and can be based on the first TRP beam configuration TRP receives wave beam, for receiving uplink signal from the UE in carrier wave 1.UE can configure the first UE wave beam and carried with receiving The first RS sent in first TRP wave beam of wave 1.In one example, UE can be based on having been used to receive from carrier wave 2 The 2nd UE wave beam for the 2nd RS that TRP in two TRP wave beams is sent configures the first UE wave beam in carrier wave 1, for receiving the One RS, wherein the first RS is spatially co-located with the 2nd RS standard.Can by RRC signaling, MAC-CE, DCI signaling, or combinations thereof UE spatially is sent with the quasi- co-located information of the 2nd RS by specified first RS.

In some embodiments, when two HF component carriers (for example, carrier wave 1 and carrier wave 2) are spatially quasi- co-located, one Wave beam management information in a carrier wave is used directly for the wave beam management of another carrier wave.For example, when TRP (or UE) is to having Transmission wave beam in the carrier wave 1 of UE (or TRP) executes when sending, TRP (or UE) can directly using transmission wave beam come with carrier wave 2 In UE (or TRP) process that is sent, and determined without beam scanning and wave beam.Come from TRP angle or from UE angle Say, when between two HF component carriers on beam direction there are when wave beam mapping, the quasi- co-located HF component carrier of two spaces Mutual and spatial calibration can be referred to as.For example, being carried when space quasi- co-located HF carrier wave 1 and carrier wave 2 are mutual and spatial calibration There are wave beam mappings between the second wave beam in the first wave beam in wave 1 and carrier wave 2.At this point, the first and second wave beams have phase With or similar spatial character (for example, identical beam direction, power distribution etc.), and when in carrier wave 1 the first wave beam (or The second wave beam in carrier wave 2) known (for example, be determined or identify) when, map wave beam accordingly, that is, the second wave in carrier wave 2 Beam (or first wave beam in carrier wave 1) also will be known.In one example, when TRP or UE identification has wave beam management When downlink or uplink beam in carrier wave 1 are to link, TRP and UE directly can form downlink in carrier wave 2 Or uplink beam is to link.If two HF component carriers are quasi- co-located but are not mutually and spatial calibration one Wave beam management information in a component carrier is still contribute to the wave beam management in another component carrier.For example, working as UE It was found that usual optimal receptions wave beam and transmission wave beam clock synchronization for communicate with TRP by carrier wave 1, be used to pass through carrier wave 2 and The wave beam management of TRP communication can be only by being held based on wave beam to execution process P-2 in the downlink and in the uplink Row process U-2 is completed.
